Scroll Event

This is a general event that is triggered for many things, such as the scroll bar is moved to a new position.  Use its arguments to drill down into getting particular events.


	private: System::Void srlTimeline_Scroll(System::Object^  sender, System::Windows::Forms::ScrollEventArgs^ e)
	{
		if (e->Type = ScrollEventType::EndScroll)
		{
			MessageBox.Show("User has finished scrolling")
		}
	}

Value Changed Event

Occurs every time the value changes (either by user or when you set the value)

Is a Scroll Bar Currently Being Dragged With The Mouse


	if (!srlTimeline->Capture)		//Don't do if scroll bar is being dragged

The Maximum Value Can't Be Reached!

The maximum value of a scroll bar can only be reached programmatically. The value of a scroll bar cannot reach its maximum value through user interaction at run time. The maximum value that can be reached through user interaction is equal to 1 plus the Maximum property value minus the LargeChange property value. So an easy way round this is to set the maximum to (Max Value + Large Change Value – 1)


	MyScrollBar->Maximum = MyMaxValue + ChartScrollBar->LargeChange - 1
